Abstract
The Soy Sauce Industry Produces Liquid Waste with High Pollutant Content, Potentially Polluting the Environment. An Alternative Treatment Using MBBR in an Anoxic-Oxic System Utilizing Indigenous Microbial Consortium and Chlorella sp. Microalgae. This Study Aims to Determine the Effectiveness of Different Types of Microorganisms in Removing Pollutants from Soy Sauce Wastewater. The MBBR (Moving Bed Biofilm Reactor) was operated with Kaldness 1 media fill variations of 20%, 40%, and 60% and sampling time variations of 14, 26, and 38 hours in continuous operation. The study found that indigenous microbes in soy sauce wastewater were more effective than the Chlorella sp. microalgal consortium. The best results with indigenous microbes showed BOD5, COD, Total Nitrogen, and Total Phosphate removal rates of 86.76%, 88.24%, 82.76%, and 79.25%, respectively, at a sampling time of 38 hours and a 40% media fill volume. For TSS, the best removal rate was 82.76% at a sampling time of 26 hours and a 20% media fill volume. For the Chlorella sp. microalgal consortium, the best reductions in BOD5, COD, Total Nitrogen, and Total Phosphate were 71.54%, 74%, 71.89%, and 73.7%, respectively, at a sampling time of 38 hours and a 20% media fill volume, with TSS reduction at 79.41% at a sampling time of 14 hours and a 20% media fill volume. The best color removal rates were achieved in the anoxic stage at 95.34%, in the oxic stage with indigenous microbes at 88.87%, and with the Chlorella sp. microalgal consortium in the oxic stage at 86.39% at a sampling time of 38 hours. Keywords: soy sauce wastewater, indigenous microbes, Chlorella sp. microalgae, MBBR, media fill, sampling time
